I have submitted the app to Apple but they rejected it because the iAd does not hide when an advert is NOT available. They said this is against app rules. Please can you tell me the code I need to replace to make this work?

I have renamed but now this Command /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang failed with exit code 1
Can you help?
If i rename the Projekt back to BugsAttack then i can build..
